For the man of leisure there is no more refined nor delightful pursuit than savouring this thick delicious nectar drop by drop on the tip of the tongue. The average person talks of 'drinking' tea, but this is a mistake. Once you have felt a little of the pure liquid spread slowly over your tongue, there is scarcely any need to swallow it. It is merely a question of letting the fragrance penetrate from your throat right down to your stomach. On no account should it be swilled round the mouth and over the teeth, for this is extremely coarse. 'Gyokuro' tea escapes the insipidness of pure water and yet is not so thick as to require any tiring jaw action. It is a wonderful beverage. Some complain that if they drink tea they cannot sleep, but to them I would say that it is better to go without sleep than without tea.
